Research on pairing-free certificateless batch anonymous authentication scheme for VANET by Cheng SONG, Ming-yue ZHANG, Wei-ping PENG, Zong-pu JIA, Zhi-zhong LIU, Xi-xi YAN

“…To solve the problem of security and efficiency of anonymous authentication in vehicular ad hoc network,a pairing-free certificateless batch anonymous authentication scheme was proposed.The public and private keys and pseudonyms were jointly generated by the trusted third party and vehicle,so the system security didn't depend on the tamper device.The scheme can realize authentication,anonymity,traceability,unforgeability,forward or backward security,and so on.Furthermore,under the random oracle model,the scheme can resist Type I and Type II attacks.Because there is no need to use certificates during authentication,the system storage load is effectively reduced.At the same time,the scheme realizes the batch message authentication on the basis of pairing-free operation,so the authentication efficiency is improved.Therefore,the scheme has important theoretical significance and application value in the resource-limited internet of things or embedded environment.…”

A ZigBee network anonymous authentication scheme based on Chebyshev chaotic mapping and CRT by Wei LIAO, Lesheng HE, Heng YIN, Shengtao YU, Jiarui QUAN

“…A ZigBee network anonymous authentication scheme based on Chebyshev chaotic mapping and Chinese remainder theorem (CRT) was proposed to solve the problems such as the incomplete reliability of ZigBee network trust center and the lack of identity authentication when accessing the network.The proposed scheme can not only realize two-way authentication of anonymous identity, but also ensure the security of key distribution when ZigBee network structure changes dynamically.It is mainly based on a ZigBee and NB-IoT wireless heterogeneous gateway, so that the server can effectively manage the nodes in the network through this gateway.From security analysis and comparison with other related literature, the proposed scheme has higher security, with anonymity and unlink ability.In addition, the results show that the proposed scheme has more advantages than other schemes on the computational overhead.…”

An improved RFID authentication protocol based on quadratic residue by Zhiliang LIU

“…In view of the existing radio frequency identification(RFID) authentication protocol based on quadratic residue in the security and cost aspects of the loopholes and deficiencies,an improved RFID bidirectional authentication protocol based on the quadratic residue was designed.The improved protocol was mixed with random number encryption under the framework of the quadratic residue,which makes the message certification and identification more efficient and fast in database authentication and identification; the ultra-lightweight bit replacement operations and XOR encryption communication information was introduced,which reduces the cost of system computing; in database,the random number checking mechanism was added to avoid attacks such as agreement to be synchronized and denial of service attacks; finally,the GNY logical proof of the protocol was given,which shows the feasibility of the improved protocol.The protocol security and performance analysis indicate that the improved protocol has higher security and lower cost.…”

Triple receiver public key encryption cryptosystem by Liutao ZHAO, Lin ZHONG, Jidong LIU, Caiqun WANG, Dan WU

“…A triple receiver public key cryptosystem was proposed.In the cryptosystem,a sender encrypted a message and sent to three receivers,while the three receivers were able to decrypt the message with their own private keys.Based on bilinear map,two triple receiver public key encryption schemes with different security were constructed.If the gap bilinear Diffie-Hellman (GBDH) problem and the computational Diffie-Hellman (CDH) problem were proved formally to be intractable,then the two schemes proposed were semantically secure against chosen-plaintext attacks and against adaptive chosen ciphertext attacks respectively.The proposed scheme only added an exponential operation and a hash operation,and constructed three independent receivers which had a high efficiency.Analyses show that proposed scheme can improve the security of TLS protocol and apply to hierarchical public key cryptosystems.…”

Attack Analysis Framework of Space-Integrated-Ground Information Network Based on Cybersecurity Knowledge Graph by Yulu QI, Rong JIANG, Xing RONG, Aiping LI

“…While realizing global coverage, random access, on-demand service, security and credibility, the space-integrated-ground information network(SGIN) is confronted with more complex and variable security threats.Compared with the internet, satellite network has a lot of diff erences, such as highly dynamic changes of topology, transfer protocol and data format.In terms of these questions, it was necessary to integrated the rule of satellite network attacks into the rules of APT attacks, developed the cybersecurity knowledge graph and the attack rules library to analyzed the attacks of the SGIN.The pattern of attack rules was expressed based on time-space data model, which was used to completed the attack chain when there were non-continuous missed data or false positives data.The attack analysis framework proposed in this paper could accurately perceived the security status of the SGIN in real time , and provided decision support for the SGIN.…”

Performance analysis of secrecy rate for SWIPT in massive antenna by Hui BAO, Minmin ZHANG, Yaqing YAO, Hui WANG

“…In the multi-drop broadcast system,the existing research is to optimize the single-user security rate in the complete channel state information.In fact,it’s impossible that there exists only one user in the system.The base station often receives incomplete channel state information.Aiming at this problem,a robust beamforming scheme was proposed.In the multi-user case,considering the influence of channel estimation error on the system security rate,the particle swarm optimization algorithm was used to optimize the emission beamforming vector,artificial noise covariance and power split ratio to ensure that the user collects a certain energy while maximizing the safe transmission rate.The simulation results show that the proposed scheme is slightly lower than the security rate in the ideal case,but it is meaningful to the actual system,taking into account the existence of eavesdropping users and the estimation error.…”

“…To reduce the security implementation cost of the outsourcing data audit mechanism for the regenerating-coding-based distributed storage systems, an orthogonal algebraic coding method was put forward to construct a lightweight privacy-preserving audit scheme based on linear homomorphic authentication.The homomorphic authentication tags were generated with the orthogonalization between the file encoded data and the private secret key vector, and the privacy protection of the auditing response message was achieved by using the random masking that was constructed by randomizing the orthogonal basis vectors of the specific sub-vector of the user’s secret key.The work realized the effective integration of algebraic coding, privacy protection, and security auditing.Theoretical analysis shows that the proposed scheme can realize the information-theoretic security in the regenerating-coding-based storage applications.Compared with the existing works, the proposed scheme is of low computational complexity and communication overhead, and better performance advantages.…”
